transponder overload
I have an Ultra that does the same thing and I have no where near that amount of channels in it. (maybe 400) but when I do a lot of blind scanning it will plug up the list and make the unit do some wacky things
Things to try
1. Since I dont use this for
C-Band, I loaded the list on ChannelMaster and removed all C-Band satellites
2. I removed almost all the TP's on each satellite. The channels will stay even if the TP is eliminated.
That seemed to help from keeping it doing that.
